Return Value

Type: SystemString
The current string.
Remarks

Because this method simply returns the current string unchanged, there is no need to call it directly. It is usually called implicitly in a composite formatting operation, as the example shows.

Examples

The following example demonstrates the ToString method. Note that the example does not explicitly call the ToString method. Instead, the method is called implicitly by the composite formatting feature.

   Public Shared Sub Main()
      Dim str1 As [String] = "123" 
      Dim str2 As [String] = "abc"

      Console.WriteLine("Original str2: {0}", str2)
      Console.WriteLine("str1 same as str2?: {0}", [Object].ReferenceEquals(str1, str2))
